SAFETY RAZOR.

Application led November 28, 1923. Serial No. 677,407.

T o all whom t may concern:

Be it known that I, FRED SnxAUnn, a citizen of the United States, and a resident df the city 0f Torrington, county of Litchfield, and State of Connecticut, have invented certain new and useful Improvements in Safety Razors, of which the following is a specification.

This invention relates to razors and more particularly to a safety razor so constructed that the correct diagonal stroke will be more easily obtained by the user.

One object of this invention is to provide a safety razor having a thin flat handle arranged in such a position that the blade will be dra-wn across the face of the user at the most efficient shaving angle.

A further object is to provide a safety razor of this nature which will be simple, cheap to manufacture, easy to manipulate, and very efficient and durable in use.

With these and other objects in view, there have been illustrated on the accompanying drawings two forms in which the invention may be conveniently embodied in practice.

Fig. 1 represents a side view of a safety razor embodying a preferred form of the invention, looking in a direction at right angles to the plane of the handle, said razor being of the Well-known Gillette type.

Fig. 2 is a top plan view of the safety razor shown in. Fig. 1.

Fig. 3 is a side view of the razor handle, showing in section the screw socket by which it is secured in position.

Fig. 4 is a sectional view of the hollow locking tube.

Fig. 5 is a top view of the razor guard.

Fig. 6 is a similar view of the razor blade.

Fig. 7 is a side view of the razor bed-plate, the base of said plate being shown partly in section.

Figs. 8 and 9 are side views of a modified form of handle, together with a razor of the well-known Autostrop type with which the handle is to be used.

Fig. 10 is a view of another modified form of handle similar to Fig. 9, but adapted for use with the Gillette type of razor.

In the use of former types of safety razors, great diiculty was experienced in holding the blade at the proper diagonal angle 'to the line of the shaving stroke, and the correct shaving stroke could be acquired only after a considerable eriod of use.

By means o the present invention the above and other disadvantages have been avoided. This has been accomplished by providing a safety razor with a flat handle set at such an angle to the blade that when the handle is drawn across the face in a straight line, the blade will automatically assume the correct diagonal position with respect to the line of stroke.

{eferring now to the drawings in which like reference numerals denote corresponding parts throughout the several views, the numeral 10 indicates a bed-plate comprising a base formed in the shape of an oblique parallelogram and having its opposite sides and ends parallel. The bed-plate 10 is crescent shape in transverse section and is provided with a pair of upstanding studs 11 and 12 near its ends, and an elongated cylindrical central post 13 having itsupper portion 13a threaded.

In order to prevent the razor blade from cutting the face of the user, a guard plate 14 is provided, said guard plate also being preferably arc-shaped in transverse section and having its exterior face adapted to fit the interior face of the bed plate 10. The guard plate 14 is provided on its opposite sides with rows of teeth 15 and 16 respectively,

said teeth preferably lying parallel to the ends of the guard plate 14, as clearly shown in Figs. 2 and 5. rThe guard plate 14, is provided with a pair of apertures 17 adapted to fit over the studs 11 and 12, and also has a depressed annular recess 18 encircling an aperture 19 within which the post 13 of the bed plate 10 is adapted to fit.

In order to clamp the guard plate 14 firmly upon the bed-plate 10 to secure a razor blade 20 therebetween, a cylindrical locking tube 21 is provided. as clearly shown in Fig. 4. The locking tube 21 is preferably knurled on its lower exterior 22, and is provided with anv upper reduced section 23. rIhe inside bore of the locking tube is preferably smooth and of uniform diameter throughout its length except for a short threaded top section 24, as shown in Fig. 4.

In order to manipulate the safety razor, a handle 25 is provided which as clearly shown in Fig. 3 consists of a thin flat finger engaging portion 2G of a generally rectangular shape, having convex corners and concave side edges. The finger-engaging section of the handle 25 is preferably knurled on its opposite faces. The handle 25 is rovided at its lower section with a hoow socket 27, tapped on its interior to engage the threads of the top 13a of the post 13.

In Fig. 8, a modified form of handle is shown, said handle being adapted to be screwed into a razor body of the Autostrop type shown in Fig. 9.v This form of handle is preferably constructed by stamping and bending from a single strip of metal and comprises a thin flat upper section 28 and .a thin fiat lower section 29, said sections 28 and 29 being at rightangles to eachother. The bottom of the lower section 29 has a rod 30 integrally secured theieto, said rod being threaded on its exterior to screw into a socket 31 of .a razor body 32. By means of the safety razor shown in Figs. 8 and 9, when it is desired to shave the leftl side of the face, the upper section 28 of the handle will be grasped by the hand of the user. When, however, the right side of the face is to be shaved, the lower section 29 of the handle will be employed.

In the operation of both forms of razor, the handle will be drawn alon the face in This will cause the edge` of the razor blade 1 to be drawn along obliquely7 to the line of stroke. The handles of the razors are preferably adjusted so that the blade will make an angle of approximately seventy-five de grees to the line of stroke, this angle having been found in practice .to bethe most ellicient.

Onev advantage of the present invent-ion' is that the improved safety razor herein disclosed may be used with equal succcess.y b unskilled as ywell as skilled persons. further advantage is that a erson shaving with the razor for the first time can obtain the correct diagonal strokev which formerly required a long period of practicing to ac# quirei y While there have been disclosed in this specification two forms in which the invention `may be embodied, it is to be understood that these forms are shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosures but may be modified and embodied .inv various other forms wthout departing from its s irit. In short, the invention includes all tie modifications and embodiments coming within the scopeof the followin claims.

Havin thus fully described t e invention, what is c aimed as new, and for which it is desired to secure Letters Patent, is:

1. In a safety razor, a blade formed in the shape of an oblique parallelogram, a bedplate to support said blade, a guard adapted to be clamped upon said bed-plate, said bedplate having a threaded post extending upwardly through said bladeand said guard,

vsaid post being threaded on itsv upper extremity, a threaded tube screwed on said post for clamping said blade between said bedplate and guard, and a handle threaded on the top of said post `for manipulating said razor.

3. In a. safety razor, a blade formed in the shape of an oblique parallelogram, a bedplate to support said blade, a guard adapted to be clamped upon said bed-plate, said bedplate having a threaded post adapted to extend upwardly through said blade and said guard, a lookin tube threaded on said post for holding sai blade clamped between said' guard and said bed-plate, and a handle threaded on thel top of said post for manipulating said razor, said handle having a thin iiat finger engaging section parallel to the ends of said4 blade, and disposed at the correct shaving anglel relative to the line of the shaving stroke.

4. In a safety razor, a blade formed in theshape of an oblique parallelogram, a holder for said blade, a guard to protect the face of the user, said holder havin a post projecting through-said. bladeran said guard,

Aa hollow tube threaded on said post, andv adapted to engage said guard to clamp said blade between said guard and said holder,

and a handle screwed on the top of said post for manipulating said razor.
